Array microphone systems and methods that can automatically focus and/or place beamformed lobes in response to detected sound activity are provided. The automatic focus and/or placement of the beamformed lobes can be inhibited based on a remote far end audio signal. The quality of the coverage of audio sources in an environment may be improved by ensuring that beamformed lobes are optimally picking up the audio sources even if they have moved and changed locations.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The method of claim 1, wherein the amount of the sound activity comprises one or more of an amount of voice, an amount of noise, a voice to noise ratio, or a noise to voice ratio.
5. The method of claim 1, wherein the predetermined criteria comprises one or more of a voice threshold, a noise threshold, a voice to noise ratio threshold, or a noise to voice ratio threshold.
7. The method of claim 6, wherein the auxiliary lobe is not available for deployment by the array microphone.
11. The method of claim 10, wherein generating the output signal comprises generating the output signal by gradually mixing the processed auxiliary lobe with one or more of the located inactive lobe or the relocated existing deployed lobe.
12. The method of claim 11, wherein generating the output signal comprises generating the output signal by gradually removing the processed auxiliary lobe from one or more of the located inactive lobe or the relocated existing deployed lobe.
14. The method of claim 1, wherein the location data of the sound activity comprises coordinates of the sound activity in the environment.
16. The method of claim 15, wherein the amount of the sound activity comprises one or more of an amount of voice, an amount of noise, a voice to noise ratio, or a noise to voice ratio.
18. The method of claim 15, wherein the location data of the sound activity comprises coordinates of the sound activity in the environment.
20. The method of claim 19, wherein the predetermined criteria comprises one or more of a voice threshold, a noise threshold, a voice to noise ratio threshold, or a noise to voice ratio threshold.
21. The method of claim 19, wherein the location data of the sound activity comprises coordinates of the sound activity in the environment.
23. The method of claim 22, wherein the location data of the sound activity comprises coordinates of the sound activity in the environment.
24. The method of claim 22, wherein the predetermined metric criteria comprises one or more of a voice threshold, a noise threshold, a voice to noise ratio threshold, or a noise to voice ratio threshold.
25. The method of claim 22, wherein the auxiliary lobe is not available for deployment by the array microphone.
26. The method of claim 22, wherein the location data of the sound activity comprises coordinates of the sound activity in the environment.
28. The method of claim 27, wherein generating the output signal comprises generating the output signal by gradually mixing the processed auxiliary lobe with one or more of the located inactive lobe or the relocated existing deployed lobe.
29. The method of claim 28, wherein generating the output signal comprises generating the output signal by gradually removing the processed auxiliary lobe from one or more of the located inactive lobe or the relocated existing deployed lobe.
30. The method of claim 27, wherein the location data of the sound activity comprises coordinates of the sound activity in the environment.
31. The method of claim 27, wherein the auxiliary lobe is not available for deployment by the array microphone.
32. The method of claim 27, wherein the location data of the sound activity comprises coordinates of the sound activity in the environment.
